摘要：
Nonlinear optical polymers made: of doping a commercially available dye, Disperse Red I (DR1), into poly(methyl methacrylate) in different weight percentages are studied by positron annihilation lifetime spectroscopy. The lifetimes acid intensities of ortho-positronium are significantly reduced with increasing dopant concentration. The glass transition temperature is also found to decrease with increasing dopant concentration.
